Abstract

具有用于饮用的适当打开位置的触觉指示的饮料容器。该饮料容器包括基部、套环和盖，该盖具有用于打开和关闭容器以倾倒/饮用的环形密封垫圈。改进之处在于位于套环上的套环止动件，以及从密封垫圈延伸的一对密封止动件，并且在密封止动件之间形成凹口。由于套环止动件与密封止动件中的前一个干涉，盖的用以打开容器的转动变得困难。继续旋转以将套环止动件坐置在凹口中可提供触觉指示，其表明盖已经转动到适当打开位置，并且可以避免进一步转动。

背景技术
本发明总体上涉及供使用者饮用的饮料容器。特别地，本发明涉及那些具有储存体的饮料容器，该储存体具有边沿、固定至该边沿的环形套环、以及螺纹连接至套环的中心开口的圆形盖。套环包括一个或多个导流小孔，并且盖在一个方向上的转动将导致盖下降，并且因此阻塞这些导流小孔以密封容器。盖沿相反方向旋转将导致盖上升，并且因此打开导流小孔以允许饮用。
使用者通常不确定打开容器饮用所需的盖的旋转的量。旋转太少将限制流动并且使其难以用于饮用。旋转太多，则担心盖意外地从套环脱落并且引起严重的溢出。已知在盖和套环上提供标记，这些标记在建议的最佳转动位置对齐，以对使用者提供视觉指示。虽然是一种改进，但是这需要目视检查。这在弱光条件下可能很困难。此外，这会在驾驶时造成分心的危险。

具体实施方式
参考图1，根据本发明的饮料容器打开指示器由附图标记10来总体上表示。容器10总体上包括基部12、套环14和盖16。基部12旨在保持饮料，并且总体上由凹形主体组成，该凹形主体具有终止于上边沿20的至少一个侧壁18。在所示的实施例中，基部12采用平底(玻璃)杯的形式，但是也可以采用其它形状和尺寸，诸如用于咖啡或茶的多杯隔离玻璃壶(multi-cup insulated carafe)。
套环14包括具有顶端24和底端26的外壁22。套环12包括与端部24和26中的每一个间隔开的向内延伸的导流壁架28，该导流壁架包括延伸穿过其的至少一个导流小孔30(图3)。导流壁架28的内边缘又安装了环形套环轴32。套环14可移除地安装至基部12。这种配合可以采用各种形式，诸如压配合或卡合，但是如图2、图8和图9中最佳所示，示出的优选布置是使上边沿20成圆形并且包括一组螺纹。导流壁架下方的套环14将包括一组配合的螺纹，使得套环14将被螺旋拧转到基部12上。该螺转连接本身就足以防止在饮用/倒入期间发生泄漏。为了确保防止泄漏，优选地包括大体环形形式的弹性环垫圈34(但是如果采用压配合，则外周缘可以是多面的、不规则多边形的或其它构造)。
可以想到，在将套环14安装至基部12的情况下，组合部件的倾斜将引起储存在基部中的液体流过一个或多个导流小孔30，并且随后流过套环14的顶端24。这将允许使用者喝到储存在基部14中的液体。然而，对于这种类型的容器，真正的效用来自可选择性地防止这种流动。这是盖16的目的。
通过图2、图4和图5最佳所示，盖16包括盖体36和安装至盖体36的密封垫圈38。盖体36包括顶板40和手柄42(图2)，以允许用手抓握和转动盖体36。在所示的实施例中，该把手42由一对间隔开的凹陷形成，并且这些凹陷之间的部分易于被使用者抓住。其它布置也是可能的，诸如向上延伸的凸脊(未显示)、一对隔开的突起(未显示)等。盖体36还包括从顶板40纵向向下延伸的盖塞44。
盖塞44旨在与套环轴32相互作用。特别地，盖塞44和套环轴32将各自包括用于彼此配合的适当螺纹。在所示的实施例中，盖塞44紧密地接纳在套环轴32内，并且因此，盖塞44在其外部包括螺纹，并且套环轴32在其内部包括螺纹。这种布置可以相反，其中套环轴接纳在盖塞内。如可以参考图8和图9所设想的，在这些螺纹啮合的情况下，盖16相对于套环14的相对转动将引起顶板40沿第一旋转方向朝着底端26向下移动，并且引起顶板40沿相反的旋转方向朝着顶端24向上移动。
导流壁架28和导流小孔30位于套环轴32的径向外部。顶板40的尺寸设计成也径向地向外延伸，以覆盖导流小孔30。盖体36还包括密封脊46，该密封脊在邻近导流小孔30的位置处从顶板40向下延伸。密封垫圈38在其顶面上包括匹配的密封沟槽48，该密封槽的尺寸设计成可接纳密封脊46，并且因此将密封垫圈38可移除地安装到盖体36。如图8和9中最佳所示，一旦安装，密封垫圈38将与导流小孔30相对。随着盖14沿适当方向的转动，盖14将朝着底端26向下移动，直到密封垫圈38邻接并且阻塞导流小孔30。在该位置，饮料容器10是水密的，并且无论其定向如何，液体都不会离开容器10。盖14沿相反方向的转动将导致密封垫圈38离开并且因此打开导流小孔30，允许使用者从饮料容器10中饮用。
为这点所描述的布置在现有技术中是众所周知的。将从这点描述本发明的特征。出于将会更清楚的原因，优选地限制密封垫圈38相对于盖体36的旋转滑动。为此，密封脊46可以形成为具有不规则的自由边缘，并且密封沟槽48具有可变的深度以与该不规则的自由边缘配合。各种布置是可能的，但是在图4和图6所示的优选形式中，密封脊将形成为具有一系列径向间隔开的齿50，并且密封沟槽48将形成为具有间隙壁52，间隙壁的尺寸和位置被设计成接纳在齿50之间的间隙内。
套环14包括呈小突起形式的套环止动件54，该小突起延伸到套环外壁22与邻近导流壁架28的套环轴32之间的环形空间中。实际上，在所示的优选实施例中，套环止动件54向下延伸以与导流架28合并。密封垫圈38中的大部分具有恒定的外径，并且其尺寸被设计成从该套环止动件54径向地向内隔开，并且因此可以相对于套环14自由地转动。但是密封垫圈38的至少一个部段包括一对密封止动件56。尽管不是必需的，但优选的是，密封止动件56是在密封垫圈38的模制期间形成的密封垫圈38的整体延伸部。密封止动件56优选地径向向外延伸一定距离，使得它们各自与套环止动件54的一部分重叠(图8中最佳示出)。换句话说，密封止动件56中的每个将引起对套环止动件54的干涉。此外，一对密封止动件56彼此间隔开一定距离以形成凹口58，该凹口的尺寸设计成允许套环止动件54被紧密地接纳在其中。正是套环止动件54进出凹口58的这种运动为使用者提供了盖位置的触觉指示。
虽然可以提供盖16的完全关闭位置(防止流动)的触觉指示，但是可以感觉到，当密封垫圈38坐置于导流壁架28时进一步转动密封垫圈38的阻力将提供足够的完全关闭的位置的触觉指示。但是盖16的适当打开位置更难以确定。显然，盖16可充分转动以使其可从基部12完全移除(例如以允许填充)，并且因此容器10将完全打开。盖16可以被转动得足以被移除的事实可能引起使用者对盖16转动多少的忧虑，以及当容器10倾斜以便饮用时，盖是否转动太多并且可能脱离套环14。可以预见，这通常会导致超出预期体积的液体(可能是非常热的液体)意外溢出容器10并且溢到使用者的脸部。术语“适当打开位置”是指盖16的相对于套环14的某个转动位置，该转动位置允许液体自由流动经过导流小孔30以便饮用，同时仍然将盖16牢固地保持至套环14以防止这种溢出。
这样，优选地，由坐置在密封止动件56之间的套环止动件54提供的触觉指示可用于确定盖16的适当打开位置。从盖16处于其最低位置并且密封垫圈38封闭导流小孔30开始，凹口58相对于套环止动件54转动地(即沿周向地)偏移。当盖朝着打开位置转动时，在密封垫圈未覆盖导流小孔30的情况下，凹口58将更靠近套环止动件54。在该转动周期中，密封垫圈38不与套环止动件54干涉，并且因此，在使用者用手转动时，盖容易转动。然而，当密封止动件56中的前一个止动件抵靠套环止动件54时，盖16相对于凸缘14的转动将变得更加困难。密封垫圈38的弹性特性，以及止动件54和56的适当的尺寸的重叠，将允许密封止动件56中的前一个充分变形以使盖继续旋转。一旦密封止动件56的前一个转动经过(并且因此不干扰)套环止动件54，将会有转动变得明显容易的短暂时刻，随后又一次，当密封止动件56中的后一个(trailing)与套环止动件54发生干涉时旋转又变得更加困难。此时，套环止动件54被接纳在凹口58内。可以预见，使用者在触觉上可注意到盖16的旋转阻力的这种变化(其中难-易-难的转动发生在指定的转动点)。此外，套环止动件54坐置在凹口58内将有助于防止盖16进一步意外的转动。
盖16从关闭位置到适当打开位置的转动的量可以变化。然而，优选的是使用者可以容易地完成转动。这样，优选的是适当打开位置与关闭位置在15度至90度之间。轻松实现此转动量而不会在手腕上产生压力。当然可以进行其它转动以到达适当的打开位置。
尽管密封止动件56可以采取许多几何形式，但是图5-7的比较可显示，在优选形式中，每个密封止动件56可采取倾斜的坡道的形式，该倾斜的坡道朝着凹口58深度增加。这将导致更平滑的凸轮作用，以使凹口58坐置在套环止动件54上的“喀哒”声对于触觉更明显。密封止动件56在套环止动件54上的运动可以完全经由密封止动件56的弹性变形来实现。然而，如图4所示，可能优选的是，去除或减小在密封止动件56下面的特定齿50(未示出)。这将允许密封垫圈38在该位置具有更大的柔性，并且因此允许密封止动件56具有更大的柔性。另外，优选的是在每次使用时都将密封垫38保持在盖体36上的相同的时钟位置，因为这将为达到适当的打开位置提供更多的可预测性，并且因此减少使用者的焦虑感。消除或减小密封止动件56下方的特定齿50允许密封止动件56下方的特定间隙壁52如图6中的60处所示具有不同的尺寸。以这种方式，密封垫圈38可以仅以期望的时钟位置安装在盖体16上，并且不能被不正确地安装。
尽管不是必需的，但还优选的是，套环轴32和盖塞44上的配合螺纹具有倾斜度，使得在将盖16安装至套环14或从套环14拆卸期间，凹口58将仅与套环止动件相互作用一次。如图8所示，当盖16关闭并且密封垫圈与导流壁架28接合以密封导流小孔30时，凹口58将从套环止动件54周向偏移，使得穿过凹口58的截面视图显示凹口58为空。随着盖子16转动以打开，盖从导流壁架28移开，直到到达如图9所示的适当打开位置。在该图中(该图再次示出穿过凹口58的截面)，套环止动件54被接纳在凹口58内。在使用优选形式并且在关闭的旋转15-90度而达到适当打开位置的情况下，可以看到，凹口58已经相对于套环止动件54升高，但是套环止动件54仍将坐置在凹口58内。给定盖16转动至适当打开位置期间的垂直运动量，可以容易地想到盖16相对于套环14的另一360度旋转将(由于螺纹角度)使密封止动件56和凹口58升高到轴环止动件54的顶部边缘上方。这样，在该优选布置中，在完全打开旋转或完全关闭旋转期间，凹口58将仅使套环止动件54坐置一次。以这种方式，避免了盖16到达适当打开位置的混乱。
从上文可见的是，本发明是一种极其适于获得上文所阐述的所有目标和目的以及其结构中所固有的其它优点的发明。
应当理解，某些特征和子组合是有用的，并且可以在不参考其它特征和子组合的情况下使用。这是权利要求书的范围所预期的并且都在权利要求书的范围内。
由于在不偏离本发明范围的前提下，本发明可具有很多可能实施例，因而应理解的是，在附图中阐述或示出的本文所有事项应理解成说明性的而没有限制的意思。
